The stability improvements of dye-sensitized solar cell with natural template for photoanode using lignin extracted from rice husk.

ABSTRACT: In response to escalating global concerns over environmental pollution, the development of green dye-sensitized solar cells (DSSCs) has emerged as a promising technology for solar energy conversion. This study harnesses the potential of rice husk, an abundant agricultural waste in Indonesia, by extracting lignin through a simple recycling method. Lignin acts as a natural, non-toxic dopant and template for TiO₂ composites, enhancing the stability of the photoanode in DSSCs. A TiO₂ photoanode modified with 5 % lignin achieved a power conversion efficiency (PCE) of 4.81 %. After a 90-day stability test, the TiO₂/lignin 5 % composite retained 78 % of its initial PCE, significantly outperforming pristine TiO₂ in terms of short-circuit current density (J_SC) and open-circuit
